Add one more to the list of Facebook apps belatedly making use of recent iPhone features. Facebook has introduced 3D Touch support to Messenger on iOS, making your iPhone 6s or 6s Plus that much more useful when you’re chatting up a storm. The update adds pressure-sensitive previews to seemingly everything — you can peek at chats, contacts, locations, media, web links and even stickers. If you want to find out whether or not that conversation or photo is worth viewing, you’ll want to get the new version right away.
